... metabolic rate (BMR), non-shivering thermogenesis (NST) and summit metabolic rate ( M sum ) increased from summer to winter, with NST and M sum already reaching maximal rates in autumn, suggesting seasonal preparation for the cold. Typical of rodents, cold-induced metabolic rates were positively correlated...

Phenotypic flexibility of metabolic rate and evaporative water loss does not vary across a climatic gradient in an Afrotropical passerine bird

... (BMR), thermoneutral evaporative water loss (EWL) and summit metabolism ( M sum ) in three populations of white-browed sparrow-weavers ( Plocepasser mahali ) along a climatic and aridity gradient. We allocated individuals to one of three T accl treatments (5, 20 and 35°C; n =11 per population per T...

Acclimatization of seasonal energetics in northern cardinals ( Cardinalis cardinalis ) through plasticity of metabolic rates and ceilings

Carrie Sgueo, Marion E. Wells, David E. Russell, Paul J. Schaeffer
Journal: Journal of Experimental Biology
J Exp Biol (2012) 215 (14): 2418–2424.

Published: 15 July 2012
... acclimatization is accomplished by coordinated phenotypic plasticity of metabolic systems. We measured summit metabolism ( V̇ O 2 ,sum ), daily energy expenditure (DEE) and muscle oxidative capacity under both winter (December to January) and breeding (May to June) conditions. We hypothesize that: (1) rates...
